BACKGROUND

1. Field of the Disclosure

This invention is generally directed to a shelf, and more particularly to a locker shelf commonly used in office, home, school dormitory and other places for storing small items such as samples, tools, documents, design drawings, bills, forms etc. in daily life. Usually a locker shelf is placed in a locker for organizing storage to improve use of locker space and to organize stored items.

2. Description of Related Art

Presently most shelf construction consists of several upright posts and predetermined amount of shelf board: To connect the shelf board and the upright post, set up screw hole is fixed at predetermined position of upright post, and the shelf board is installed to the upright post by screws and other fasteners to finish the fixed composition of shelf directly. Because all parts are fixed, the space cannot be changed by adjusting the shelf position flexibly according to needs. Besides, the stress of this shelf is concentrated at the connection part between screw and screw hole, as a result, the construction strength is not enough to bear heavy loading, which limits the practical value of shelf. The storage space of locker with above shelf is single pattern because the space cannot be adjusted flexibly, which limits the storage function of locker.

Designing a new locker shelf is necessary to improve the locker storage capacity and to provide a firm structure, and to make it easy for assembling and disassembling shelf to be placed in locker by adjusting the space flexibly according to needs.
